The document discusses the perceptions of lighting color and temperature among baby boomers and millennials, focusing on how these elements influence their feelings about interior spaces. It explores current lighting metrics, generational preferences, and the impact of advanced technology on lighting choices. The findings suggest a shift in preference towards cooler lighting temperatures in various environments despite traditional design practices favoring warmer lighting.

- 27. Perceptions of LED Light and Color In the U.S., the two largest generations are: Baby Boomers and Millennials
- 28. Baby Boomers (born between 1946 and 1964) Have lived most of their lives with warm-toned incandescent light, developed in 1880 and phased out of production in 2009. (Color Temp: 2700K)
- 29. Millennials (born between 1982 and 2004) Grew up with a prevalence of cool-toned compact fluorescent (CFL: mid 1980’s) or LED light developed in the mid 1990’s with widespread commercial installation occurring in early 2000’s. (Color Temp: 3000 - 6500K)
- 30. Technology Advancements The use of personal handheld devices, which utilize LED technology, has increased 33% over the past four years. The Millennial generation has grown up with a very different perception of light than previous generations.
